nixos/tests/{sway,cage,cagebreak}: Fix the tests on aarch64-linux

Browse Source 
Since the update to wlroots 0.13 (e03dde82a7) the default VGA card
isn't supported anymore and we needed to switch to virtio (qxl didn't
work either). However, as it turned out "-vga virtio" (28b8cff301)
broke the test on AArch64. Luckily there's a third option that works on
all three supported platforms: virtio-gpu-pci

According to [0] "This device lacks VGA compatibility mode but is
otherwise identical to the virtio vga device. UEFI firmware can handle
this, and if your guests has drivers too you can use this instead of
virtio-vga. This will reduce the attack surface (no complex VGA
emulation support) and reduce the memory footprint by 8 MB (no pci
memory bar for VGA compatibility). This device can be placed in a PCI
Express slot."
So in the end this seems like the ideal choice :)
See also [1].
